I apologize if this question has been asked before but I couldn't find the answer through a search. I have a '02 Maxima and I've replaced the factory components in front and I just bought the db650 for the rear. I'm currently running the components off of my factory headunit and will be installing the db650's soon along with an 4-ch amp. Here's my problem...not that I expected the aftermarket components to sound like a sub but there is even less bass than with the factory speakers. I'm curious if adding the polks's to the rear will compound this problem or will they provide at least the same amount of bass as before.
Also, I've heard numerous people on various sites write that the db650's were great speakers but didn't produce much bass. I'm not looking for sub-type bass, just something to sound decent. Do they mean that compared to subs they don't produce much bass or compared to stock speakers? I'm not sure what they mean by "not much bass".
Lastly, will the addition of an amp make a noticable difference in the sound of aftermarket speakers despite still using a stock headunit?
I know this is sort of jumbled and confusing but my problem is just that.
